• Close all drains and valves that were opened during winterization.
• Perform any annual maintenance not performed during winterization. See the
Engine Operator’s Manual and all equipment manufacturers’ information for
periodic and annual maintenance procedures.
• Check the engine’s cooling water intake areas and screens (if equipped) for
obstructions.
• If the engine uses a self-contained cooling system and was drained for storage,
fill the system with fresh coolant solution. Check the Engine Operator’s Manual
for specific procedures.
• Check all engine exhaust connections for exhaust leakage or damage.
• Check and lubricate the steering system.
• Check all navigational lights.
• Check all controls, gauges, boat systems, accessories and related equipment
for proper operation.
• Check all fire extinguishers for charge level.
• Inspect all safety equipment for condition and operation as applicable.
• When possible, briefly start and run the engine(s) using proper water supply
equipment to check that the engine does start and there are no major
operational problems. NOTICE: If fogging oil was used during winterization, the
engine will emit excessive white smoke upon initial start-up. This condition is
normal and will diminish once the fogging oil has been cleared through the
engine.
• Once the boat is in the water, start the engine.
• When the engine starts, watch gauge readings closely, checking for leaks and
abnormal noises.
• Keep speeds low for the first 15 minutes until the engine has reached normal
operating temperature.
• See the Engine Operator’s Manual and all equipment manufacturers’
information for additional recommendations.
